Abstract
A resin includes a cured product of a polymerizable composition including a compound represented by the following general formula (1) and a thiol compound having one or more mercapto groups, and a biomass degree of the resin is 15% or more. In the general formula (1), each of R1 and R2 independently represent a hydrogen atom or a methyl group, and n represents an integer of 0 or 1.
Claims
exact text as granted — not AI-modified1 . A resin, comprising a cured product of a polymerizable composition including a compound represented by the following general formula (1) and a thiol compound having one or more mercapto groups,
wherein a biomass degree of the resin is 15% or more:
wherein, in the general formula (1), each of R 1 and R 2 independently represent a hydrogen atom or a methyl group, and n represents an integer of 0 or 1.
2 . The resin according to claim 1 , wherein the compound represented by the general formula (1) includes 2,5-bis(isocyanatomethyl)furan represented by the following formula (2):
3 . The resin according to claim 1 , wherein the biomass degree of the resin is 35% or more.
4 . The resin according to claim 1 , wherein the thiol compound includes at least one compound selected from the group consisting of 4-mercaptomethyl-1,8-dimercapto-3,6-dithiaoctane, 4,8-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane, 4,7-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane, and 5,7-dimercaptomethyl-1,11-dimercapto-3,6,9-trithiaundecane.
5 . The resin according to claim 1 , wherein the polymerizable composition further includes an episulfide compound having one or more episulfide groups.
6 . The resin according to claim 1 , wherein a refractive index ne of the resin is 1.650 or more.
7 . A molded body, comprising the resin according to claim 1 .
8 . An optical material, comprising the molded body according to claim 7 .
9 . A lens, comprising the molded body according to claim 7 .
10 . 2,5-bis(isocyanatomethyl)furan, having a biomass degree of 50% or more.
11 . 2,5-bis(isocyanatomethyl)furan, derived from 2,5-bis(aminomethyl)furan obtained from a biomass raw material.
12 . A polymerizable composition, comprising the 2,5-bis(isocyanatomethyl)furan according to claim 10 .
13 . The polymerizable composition according to claim 12 , further comprising a thiol compound having one or more mercapto groups.
14 . The polymerizable composition according to claim 12 , further comprising an episulfide compound having one or more episulfide groups.Join the waitlist — get patent alerts
